With most of us spending at least half of the day sitting, more than ever, it’s important that we do it right.

Those tiny, repetitive movements that we all do at our desk jobs tend to add up after a while- not to mention, giving us sore shoulders and a headache.

Here are five tips to keep you sitting right, and less exhausted at the end of the day:

1. Use your sitting bone, that’s what it’s for! – your feet should be on the floor, with your knees and hips bent at about 90 degrees. This will distribute the weight off of your thighs and on to a more solid part of your body.

2. Leave some room to move – make sure to have about four fingers-worth of space behind the back of your knees and the front of the seat. Otherwise, you might end up sitting too far toward the front of the chair, and end up slouching when you get tired.

3. Moral support – adjust the armrests so that they support your elbows and arms at 90 degrees. Otherwise, if the rest is too high or low, you’ll be using your shoulders to make up the added difference.

4. No Stretch Armstrong here – When your armrest is perfect and you’re sitting straight at your desk, your fingers should be able to touch the keyboard without stretching.

5. Take a hike! – Make sure to get out of your chair at least once an hour and walk around, or kill two birds with one stone and walk & work with a treadmill desk like the Walkstation. Your body will be able to stretch, get your blood flow moving, and reenergize you.
